Description

Avanos MIC-KEY Low-Profile Gastric-Jejunal (GJ) Feeding Tube kits provide skin-level enteral access for patients requiring post-pyloric feeding with simultaneous gastric decompression or venting. The device is placed through a gastric stoma with the distal limb positioned in the jejunum, offering discreet, low-profile comfort for pediatric and adult patients.

Design and retention

• Low-profile “button” with external bolster and an internal inflatable balloon for retention.
• Three clearly labeled access points: JEJUNAL (feeding), GASTRIC (decompression/venting), and BAL (balloon inflation/deflation).
• One-way valves in the JEJUNAL and GASTRIC ports that open when a MIC-KEY extension set is attached.
• No dedicated medication port; medications are administered via the jejunal or gastric port per clinical direction.

Connectivity and kit components

• Enteral-only connectivity options: ENFit or legacy Catheter Tip (varies by model).
• Kits include matching MIC-KEY extension sets; ENFit kits include ENFit extension sets.
• Extension sets available for continuous or bolus feeding, as clinically directed.

Key features

• Weighted jejunal portion to help maintain jejunal placement.
• Multiple jejunal exit ports for distribution.
• Radiopaque stripe for imaging visibility.
• Tapered distal tip to aid placement.
• Clearly marked gastric and jejunal ports.

Materials and regulatory information

• Medical-grade silicone; latex-free.
• Sterile (gamma sterilized).
• Single-use; prescription device (Rx only).

Ports and functions

• JEJUNAL port: for post-pyloric feeding.
• GASTRIC port: for decompression/drainage via low intermittent suction or gravity, as ordered.
• BAL port: for inflation/deflation of the internal balloon.

Sizes and options

• French sizes: 14, 16, 18, 22 Fr.
• Jejunal lengths: 15, 22, 30, 45 cm (availability may vary by diameter).
• Stoma length options: approximately 1.0 to 7.0 cm (availability varies by model).

Clinical handling considerations

• Placed through an existing gastrostomy with the distal tip positioned in the jejunum.
• Do not rotate G‑J tubes due to displacement risk; if movement is necessary, move very gently in and out about 1 cm.
• Maintain patency with regular sterile‑water flushes (before/after feeds and medications and periodically during continuous feeding) using a push‑pause technique.
• Jejunal feeds are typically delivered slowly by continuous infusion using an enteral feeding pump; follow local protocols and clinician direction.
